I'me not bragging! I'me concerned. I have been flushing my cooling system every 30 to 40k. I just finished checking my delta's with AE and at 65-70 with engine all warmed up I was getting at max 1.5 to 2 degrees difference. At times with my the EOT would even meet the ECT. Do I have a problem or is my cooling system in peak ship shape?
I have a DieselSite filter and am still using Ford gold coolant.

 

Don't you dare complain!!!! LOL Hey man, it's perfect! Do you tow? Be curious to see what it does when REALLY being worked.

 

Wow! U have every Powerstroke owners dream..............

 

I just looked at a 2007 F350 for a buddy of mine with 132K, it wasn't much different. I was shocked!

 

No I don't tow. This truck is my baby and toy. It has towed a couple times. Heaviest was a 7K trailered skid steer. Last month a 5K tailer camper, about 1500 miles. That's it. My only issue right now is getting my ESOF (auto) working correctly.
See my other post HERE.

 

My ECT and EOT are within 2 to 5 degrees.. untill I romp on it then they start spread out 10 to 12. till I stop rompin on her then they come back together... what kind of oil are you using BTW?

 

Now that's cool....

 

Rotella T6 5w-40 since my third oil change. Every 3K (5klm).

 

I'm right there with you.I see anywhere from 2* spread too about 5*-6* on the highway.I just did my first flush at 36,500 and I put the gold back in.

 

I will only see a 2-5 deg difference also....I wasnt sure if it was okay or not but I am sure it is....

Heading to the camp ground this afternoon, I saw EOT 186, ECT 184, my TFT was 149deg.

I only have done one flush and have 209,800 miles on it

Guess I cant complain either..lol

 

IMO Your temps are low.

 

It was only 45deg outside...

 

It was only 45DEG outside F

 

HV: what's the temp spread of your ECT/EOT prior to first start of the day after an overnight cold soak? Are they within 2-3 degrees?

 

just got my scangauge and took my truck on a long drive, once it got up to temp my temp were both steady around 190, did not stray more than 7 degrees except when I climbed a long hill, giving it plenty of throttle, the eot maxed out around 211 and the ect around 201, and as soon as i crested the hill both promptly dropped back down to 190.
